Rainier is a cultivar of cherry. It was developed in 1952 at Washington State University by Harold Fogle, and named after Mount Rainier. It is a cross between the 'Bing' and 'Van' cultivars. 'Rainiers' are considered a premium type of cherry. They are sweet with a thin skin and thick creamy-yellow flesh.

Please note that it is normal that the rainier cherry will have some brown blemishes on the surface as it is more fragile as compared to the red cherry.
